Popis: In this article, we are interested in the X-rays images of the spinal column in various positions. The purpose of this work is to extract some parameters determining the vertebral mobility and its variation during flexion-extension movements. A modified Discrete Dynamic Contour Model (DDCM) using the Canny edge detector was the starting point for our segmentation algorithm. To address the lack of convergence due to open contour, we have elaborated a heuristic method appropriate to the area of our application. The results in real images cooresponding to the cervical spinal column and their comparison with manual measures are presented to demonstrate and to validate the proposed technique.
